This paper attempted to explore a high accuracy topic delection method for Chinese microblog for quickly detecting hot topics in Chinese microblog. Firstly, It took optimizing the text feature selection into consideration. The different parts of speech of these features obtained from analysis were very important to topic expression. Secondly, on this basis, it proposed a scoring mehod to filter out those topic-unrelated tweets. It used the method to dimension reduction by high-dimensional data. Fi-nally, it introduced the idea of keywords on the basis of Single-Pass clustering algorithm. It selected the keywords according to the feature weight of center vector. Then it used the method to detect topics by combining the outlier pretreatment with Single-Pass. Compared with the typical Single-Pass clustering algorithm, it shows that this method effectively remove the outliers of the dataset in the experiment. What's more, it not only exhibits lower missing rate and lower false detection rate on the test corpus from Sina Weibo, but also performed better in terms of time loss. [ABSTRACT FROM AUTHOR]

Aiming at the problem that the traditional protocol anomaly behavior detection is designed for specific protocol or application and is not interchangeable, this paper proposed a conditional random field (CRF) based protocol anomaly behavior detection algorithm. It extracted application protocol keywords and their intervals from network data stream as state feature, then took into account the frequent distribution of key words, finally modeled application behavior based on CRF and determined the behavior deviated from the model to be abnormal. Compared to the traditional model based on hidden Markov mode-ling method, this method does not have to make the feature quantity strict independence assumption and has multi-feature integration advantages. Experimental results show that the proposed method can detect the abnormal application behavior with high accuracy and low false alarm rate. [ABSTRACT FROM AUTHOR]

In order to reveal the breakage mechanism of roof strata in roadway mining,a continuous deep beam model under uniformly distributed load is established and its stress distribution is analyzed. Based on the mechanical properties of roof strata structure, the determination theory and method of upward mining above widespread mined-out area of roadway mining is proposed, and the influence height of No.8 coal seam in Hulonggou colliery is 8.8 m by theoretical calculation.The feasibility of roadway mining of No.5 coal seam is further studied using FLAC2D software, the results show that the height of stress weakening factor contours increases as the number of strips increases, however, when the number of strips is greater than four, the stress weakening factor would not increase any more, and the influence height of No.8 coal seam in Hulonggou colliery is 10 m. Theoretical calculations and numerical simulations show that the influence height of No.8 coal seam in Hulonggou colliery is less than 25-30 m, the coal layers spacing,so upward mining above widespread mined-out area is feasible. The study also has a certain reference value to feasibility analysis in roadway mining under similar conditions. [ABSTRACT FROM AUTHOR]

Aiming at the problem that the efficiency and performance of traditional feature selection are not compatible and it cannot be well applied to high-dimensional data, this paper proposed a neighborhood analysis based weighted feature selection algorithm (ENFSA). ENFSA created a candidate feature set based on information gain to reduce the number of dimensions. Then it assessed the redundancy and relevance of features based on neighborhood analysis and used them to update feature set and weight vector. This assessment and update process would be repeated until optimal result was obtained. Experimental results on 10 typical datasets show that this method has good efficiency and performance, and it do better on high-dimensional dataset than other algorithms. [ABSTRACT FROM AUTHOR]

In order to effectively detect application layer abnormal interactive behavior, this paper proposed a detection method based on protocol semantics sequences. First, it described the application layer interactive behavior with protocol semantics sequences and analyzed the existent abnormal interactive situations. Then, it proposed a method for anomaly detection based on protocol semantics sequences. According to the direction and order of packets, it built a set of standard protocol semantics sequences and obtained characteristics of normal behavior. After defining detection rules with abnormal interactive situations, it implemented application layer interactive behavior anomaly detection with sequence comparison and decision tree algorithm. The experimental results show that the method has a higher detection rate and lower error rate. [ABSTRACT FROM AUTHOR]

On the basis of analyzing the component characteristics of the domain of supply chain network, dynamic model for the risk spreading in supply chain network is established and the steady-state solution is given in this paper. The dynamic model consists of a set of equations and sets up risk generation term and annihilation term. The probability of risk transmission between the subjects of supply chain network is considered and the threshold of infection risk of subjects in supply chain network is set. The model can reflect the mechanism of risk spreading in supply chain network; also can reveal the change of properties of risk spreading in the structure evolution of supply chain network. The dynamic model is applied in actual agricultural products supply chain network. The properties of risk spreading of the agricultural products supply chain network and the properties of risk spreading of its evolution structure are obtained through the application of the dynamic model.

It is easy to judge the ascription of a decision object when the values of each components of decision coefficient vector with distinguished difference. But the true valuable problem is that the values of some components of decision coefficient vector without distinguished difference. Here we show a novel method to solve the existing decision paradox that the decision according to the maximum components of a decision coefficient vector may be conflicts with the result of evaluating the decision coefficient vector integratedly. We define both the weight vector group of kernel clustering and weighted coefficient vector of kernel clustering for decision-making at first. Then a novel two-stage decision model with the weight vector group of kernel clustering and weighted coefficient vector of kernel clustering for decision-making is put forward, and several functional weight vector group of kernel clustering are given. This method can effectively solve the decision paradox of rule of maximum value and produce consistent results. To demonstrate its effectiveness, a practical application is implemented for research excellence framework of UK. [ABSTRACT FROM AUTHOR]

To solve the problem of roadway maintenance in ultra-soft coal seams, the roadways in No.9 coal seam at Luling Coal Mine, China were investigated in this study. The characteristics of load distribution on the U-steel and the roadways deformation before and after the usage of pressure-released boreholes and leg-locked bolts were modeled using FLAC5.0. The results show that the stability and bearing capacity of U-steel was significantly improved after the shed's legs being locked, but the roadway deformation was not significantly reduced, which meant only leg-locked bolts could not control the severe deformation of the roadway. As the pressure-released boreholes could reserve a certain free space for rock hulking deformation, which could relieve the pressure acting on U-steel, with the collaborative action of both pressure-released boreholes and leg-locked bolts, the supporting capability of U-steel could be effectively improved. The result of field survey showed the average speed of floor heave and rib to rib deformation during mining were reduced from 2.0 mm/d, 2.64 mm/d to 0.98 mm/d, 1.86 mm/d respectively, which meant it could maintain the stability of roadways in ultra-soft coal seam effectively.
